Deep Dive
MS-721 is the deep-voice sibling of MS-700: where the Teams admin exam touches telephony, this one lives in it - and telephony is where generalist M365 admins run out of road.
The bank is dominated by voice engineering decisions: Direct Routing SBC configuration and certificate requirements, Calling Plans versus Operator Connect trade-offs, dial plans and normalisation rules, emergency calling with dynamic locations, and auto attendant/call queue design. Then the rooms layer - Teams Rooms deployment, device management, and the meeting-quality troubleshooting workflow through CQD.
It's a smaller pool than MS-700 but a far more specialised one, with prep material to match. This PDF has 300 real questions from the actual MS-721.
